BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to migrating network identities. Specifically, the invention relates to computer program products and methods for migrating network identities to a centralized management server.

2. Description of the Related Art

A single organization may have multiple computer networks. For example, a business may have a separate network for the Human Resources department, the Accounting department, and the Sales department. For a single user to log on to each network, the user must have a user identity registered with each network. As the number of network identities increases, so does the difficulty of managing the identities and the difficulty for each employee to remember their user identification information. Consequently, consolidating identities from multiple networks into a single management system is beneficial.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

It will be readily understood that the components of the present invention, as generally described and illustrated in the Figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the apparatus and method of the present invention, as represented in the attached Figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module of executable code could be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.

In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

The features, structures, or characteristics of the invention described throughout this specification may be combined in any suitable manner in one or more embodiments. For example, reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” or similar language throughout this specification do not necessarily all refer to the same embodiment and the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Turning now to the figures, FIG. 1 is a block diagram of one embodiment of an identity migration program 100 and associated datastore 105 in accordance with the present invention. The identity migration program 100 a project management module 110, an identity selection module 120, a scheduling module 130, a communication module 140, a group management module 150, an account mapping module 160, a migration process management module 170, and an execution module 180. The identity migration program 100 facilitates migrating locally-managed identities to centrally-managed identities. The modules of the identity migration program 100 may be located on a single computer or distributed among various computing components within an enterprise.

The project datastore 105 is the repository for data related to migration projects. In the depicted embodiment, the project datastore 105 is a database. In one embodiment, the project datastore 105 receives data from the communication module 140 that was received by the various modules of the identity migration program 100, whether entered by users or gathered from locally-managed or centrally-managed servers. In one embodiment, the project datastore 105 archives copies of identity migration maps distributed to locally-managed or centrally-managed servers.

The project management module 110 accepts input, validates the received data, and stores data associated with managing identity migration projects. In various embodiments, data collected by the project management module 110 includes a project name, a project description, and credentials for authenticating to source and target systems. The project management module 110 may receive project-related data from other modules of the identity migration program 100 to be stored in a project data store 105 or the like.

The identity selection module 120 facilitates selecting locally-managed identities to be migrated to centrally-managed identities. In one embodiment, the identity selection module 120 provides interface controls, and receives and validates input from the user directing the identity migration program 100 to search for locally-managed computers on a network and extract identity information from the computers. The identity selection module 120 may utilize the communication module 140 to fulfill the user requests, display identity data retrieved by the communication module 140, and accept input from the user to select identities to be migrated.

The scheduling module 130 facilitates scheduling of identity migration projects. In one embodiment, the scheduling module 130 provides interface controls to run an identity migration project immediately, at a specified time in the future, or on a periodic schedule. In one embodiment, the scheduling module 130 utilizes features of the host operating system to schedule the migration project. In another embodiment, the scheduling module 130 registers the project with a background (“daemon”) process that directs the execution module 180 to executes the scheduled migration project.

The communication module 140 manages communication between modules of the identity migration program 100 and various external entities. In one embodiment, the communication module 140 receives requests from the identity selection module 120 to retrieve identities from locally-managed computers specified by a user. In one embodiment, the communication module 140 receives identities from migration agents located on locally-managed systems. The communication module 140 may communicate an identity map to a server. In one embodiment, the communication module 140 displays an interface control that enables the user to select a server to which the identity map is to be communicated. In various embodiments, the communication module 140 retrieves data required by the various modules of the identity migration program 100, such as group membership data, identity attributes, resources associated with an identity, or the like. In various embodiments, the communication module 140 may communicate identity maps to migration agents on locally-managed or centrally-managed servers. The communication module 140 may also communicate with an external database configured to store migration project data.

The group management module 150 provides an interface control that enables the user to specify locally-managed accounts to be migrated to centrally-managed account groups. In one embodiment, the group management module 150 migrates locally-managed account groups to centrally-managed account groups in an automated process not requiring direct user input. One skilled in the art, however, will recognize that identity groups are conceptually different in various identity management and directory services systems, and identity group migration is best accomplished with user input. For example, Active Directory groups are hierarchical and different permissions can be granted at different nesting levels. UNIX groups cannot be nested. Active Directory groups have security identities (SID) that are guaranteed to be unique across an enterprise. The UNIX group ID (GID) is an integer that can easily coincide with the IDs of groups in other source repositories.

The account mapping module 160 provides an interface control to manually correct identity migration errors. Application of identity migration rules may result in multiple accounts belonging to the same person with different IDs, or identities belonging to multiple users may be migrated to the same account. When many of these identity migration errors occur, the most efficient approach may be to modify identity migration rules to produce fewer migration errors. When few migration errors occur, the most efficient approach may be to manually correct the errors and map locally-managed identities to the correct centrally-managed identities. In one embodiment, the account mapping module 160 displays a list of locally-managed identities and the centrally-managed identities to which they are mapped. The account mapping module 160 may also provide interface controls to unmap a locally-managed identity from a centrally-managed identity and remap it to a different identity or to create a new identity to which to map it.

The migration process management module 170 provides interface controls that enable the user to monitor and control the status of migration projects. In one embodiment, the migration process management module 170 provides a control to enable the user to specify conditions that cause the migration process to be interrupted. The user may then check the progress of the migration project and execute other programs to perform necessary operations not performed by the identity migration program 100. The migration process management module 170 then provides a control to resume the migration project. In one embodiment, the migration process management module 170 provides controls to verify, commit, or roll back a migration project.

The execution module 180 executes the migration project according to the migration rules and schedule specified for the project. In one embodiment, the execution module comprises processes distributed among various computing components within an enterprise, such as locally-managed servers, a migration server, and centrally-managed servers.
